We were 4 people, a couple and two teens. For 4 guests the flat is not so comfortable due two reasons. 1) there is one bathroom; 2) the second bedroom is too small for two beds.
Besides when we arrived the wardroves were almost full of belongings doing our stay a bit more uncomfortable.
Flat is far for the city but very well communicated by subway (5 minutes walking from the closest station). The building is guarded 24 horas and the neighbourhood has a lot of restaurants, food stalls and supermarkets, laundry ...
When we arrived the cleaning was not reasonable so we spoke to Dao and he solved everything sending a cleaner team whitin 24 horas. He also offered us a compensation that we are looking forward to receive whitin the next days.
We love Bangkok and we will go ba ckbto this flat if we were two or three people.
According to my experience in Airbnb the value for money is in balance. We payd 53 euros per day in august 2014.
